This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "GNU Autoconf source repository".

commit c14e7a1c8a936f1a05634ee8fe72298a5b0fdc9b
Author: Ralf Wildenhues <address@hidden>
Date: Wed Jun 23 19:18:14 2010 +0200
Coverage for Fortran compiler macros.
* tests/fortran.at (AC_OPENMP and Fortran 77)
(AC_OPENMP and Fortran): Simplify, using AT_CHECK_CONFIGURE.
(AC_F77_DUMMY_MAIN usage, AC_FC_DUMMY_MAIN usage)
(AC_F77_MAIN usage, AC_FC_MAIN usage, AC_F77_FUNC usage)
(AC_FC_FUNC usage, AC_FC_SRCEXT usage, AC_FC_FREEFORM): New
tests.
* doc/autoconf.texi (Fortran Compiler): Use GNU coding style
on C code snippets. Add markers for tested examples.
Suggest AC_FC_FREEFORM for source file extensions which the
compiler might not natively support but which are accepted
with help from AC_FC_SRCEXT. Suggest AC_CONFIG_HEADERS for
setups using one of the AC_*MAIN macros.

commit ae8dbe8995bdf4cb93ed4834c66b6ee20e35cced
Author: Ralf Wildenhues <address@hidden>
Date: Sat Jun 19 20:17:09 2010 +0200
Accept any nonzero exit status upon config.status write failure.
* tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
Normalize nonzero status to 1 for writing to /dev/full, for HP-UX
11.31 cat which exits 2.

commit 0390d6724ce64c7f3e60aceecb594f06085f8fb2
Author: Ralf Wildenhues <address@hidden>
Date: Sat Jun 19 17:49:21 2010 +0200
Fix testsuite failure with Tru64 preprocessor.
* tests/compile.at (Order of user actions and cleanup): Add
incomplete comment to provoke failure with Tru64/OSF 5.1 cc
preprocessor.
